Success of susceptibility-guided eradication of Helicobacter pylori in a region with high secondary clarithromycin and levofloxacin resistance rates

BACKGROUND Resistance to clarithromycin(CLA)and levofloxacin(LFX)of Helicobacter pylori(H.pylori)is increasing in severity,and successful eradication is essential.Presently,the eradication success rate has greatly declined,leaving a large number of patients with previous treatment histories.AIM To investigate secondary resistance rates,explore risk factors for antibiotic resistance,and assess the efficacy of susceptibility-guided therapy.METHODS We recruited 154 subjects positive for Urea Breath Test who attended The First Affiliated Hospital of China Medical University between July 2022 and April 2023.Participants underwent a string test after an overnight fast.The gastric juice was obtained and transferred to vials containing storage solution.Subsequently,DNA extraction and the specific DNA amplification were performed using quantitative polymerase chain reaction(qPCR).Demographic information was also analyzed as part of the study.Based on these results,the participants were administered susceptibility-guided treatment.Efficacy was compared with that of the empiric treatment group.RESULTS A total of 132 individuals tested positive for the H.pylori ureA gene by qPCR technique.CLA resistance rate reached a high level of 82.6%(n=109),LFX resistance rate was 69.7%(n=92)and dual resistance was 62.1%(n=82).Gastric symptoms[odds ratio(OR)=2.782;95%confidence interval(95%CI):1.076-7.194;P=0.035]and rural residence(OR=5.152;95%CI:1.407-18.861;P=0.013)were independent risk factors for secondary resistance to CLA and LFX,respectively.A total of 102 and 100 individuals received susceptibility-guided therapies and empiric treatment,respectively.The antibiotic susceptibility-guided treatment and empiric treatment groups achieved successful eradication rates of 75.5%(77/102)and 59.0%(59/411)by the intention-to-treat(ITT)analysis and 90.6%(77/85)and 70.2%(59/84)by the per-protocol(PP)analysis,respectively.The eradication rates of these two treatment strategies were significantly different in both ITT(P=0.001)and PP(P=0.012)analyses.CONCLUSION H.pylori presented high secondary resistance rates to CLA and LFX.For patients with previous treatment failures,treatments should be guided by antibiotic susceptibility tests or regional antibiotic resistance profile.

Vonoprazan-amoxicillin dual regimen with Saccharomyces boulardii as a rescue therapy for Helicobacter pylori:Current perspectives and implications

Yu et al’s study in the World Journal of Gastroenterology(2023)introduced a novel regimen of Vonoprazan-amoxicillin dual therapy combined with Saccharomyces boulardii(S.boulardii)for the rescue therapy against Helicobacter pylori(H.pylori),a pathogen responsible for peptic ulcers and gastric cancer.Vonoprazan is a potassium-competitive acid blocker renowned for its rapid and long-lasting acid suppression,which is minimally affected by mealtime.Compared to proton pump inhibitors,which bind irreversibly to cysteine residues in the H+/K+-ATPase pump,Vonoprazan competes with the K+ions,prevents the ions from binding to the pump and blocks acid secretion.Concerns with increasing antibiotic resistance,effects on the gut microbiota,patient compliance,and side effects have led to the advent of a dual regimen for H.pylori.Previous studies suggested that S.boulardii plays a role in stabilizing the gut barrier which improves H.pylori eradication rate.With an acceptable safety profile,the dual-adjunct regimen was effective regardless of prior treatment failure and antibiotic resistance profile,thereby strengthening the applicability in clinical settings.Nonetheless,S.boulardii comes in various formulations and dosages,warranting further exploration into the optimal dosage for supplementation in rescue therapy.Additionally,larger,randomized,double-blinded controlled trials are warranted to confirm these promising results.

Efficacy of a therapeutic strategy for eradication of Helicobacter pylori infection

AIM: To determine the efficacy of our therapeutic strategy for Helicobacter pylori (H. pylori) eradication and to identify predictive factors for successful eradication. METHODS: From April 2006 to June 2010, we retrospectively assessed 2428 consecutive patients (1025 men, 1403 women; mean age 55 years, age range 18-92 years) with gastric histology positive for H. pylori infection referred to our unit for 13-C urea breath test(UBT), after first-line therapy with proton pump inhibitor (PPI) b.i.d. + amoxicillin 1 g b.i.d. + clarithromycin 500 mg b.i.d. for 7 d. Patients who were still positive to UBT were recommended a second-line therapy (PPI b.i.d. + amoxicillin 1 g b.i.d. + tinidazole 500 mg b.i.d. for 14 d). Third choice treatment was empirical with PPI b.i.d. + amoxicillin 1 g b.i.d. + levofloxacin 250 mg b.i.d. for 14 d. RESULTS: Out of 614 patients, still H. pylori-positive after first-line therapy, only 326 and 19 patients respectively rechecked their H. pylori status by UBT after the suggested second and third-line regimens. "Per protocol" eradication rates for first, second and thirdline therapy were 74.7% (95% CI: 72.7%-76.4%), 85.3% (95% CI: 81.1%-89.1%) and 89.5% (95% CI: 74.9%-103%) respectively. The overall percentage of patients with H. pylori eradicated after two treatments was 97.8% (95% CI: 97.1%-98.4%), vs 99.9% (95% CI: 99.8%-100%) after three treatments. The study found that eradication therapy was most effective in patients with ulcer disease (P < 0.05, P = 0.028), especially in those with duodenal ulcer. Smoking habits did not significantly affect the eradication rate. CONCLUSION: First-line therapy with amoxicillin and clarithromycin produces an H. pylori eradication rate comparable or superior to other studies and secondline treatment can still be triple therapy with amoxicillin and tinidazole.

<i>Lactobacillus</i>GG Supplementation on Anti-<i>Helicobacter pylori</i>Therapy-Related Side Effects and Eradication Rates: A Meta-Analysis

Background: Concerns still exist with respect to unsatisfactory eradication rates and/or therapy-associated side effects for the use of standard triple therapy in the treatment of Helicobacter pylori infection, which prompts considerable interest in new therapy. We systematically reviewed the literature to investigate whether Lactobacillus GG as supplementation to standard triple therapy could improve H. pylori eradication rates and/or reduce therapy-associated side effects. Methods: PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched from their inception to August 4, 2015 for randomized controlled trials (RCTs). The language was restricted to English only. Results: Four RCTs involving a total of 305 participants (including 83 children) were included. Lactobacillus GG given along with triple therapy significantly reduced the risk of overall H. pylori therapy-related adverse effects (three RCTs, n = 221, RR 0.59, 95% CI 0.45 - 0.78), particularly of diarrhea (four RCTs, n = 285, RR 0.23, 95% CI 0.11 - 0.47), bloating (four RCTs, n = 289, RR 0.61, 95% CI 0.41 - 0.90), and taste disturbance (four RCTs, n = 288, RR 0.38, 95% CI 0.23 - 0.62). There were no significant differences between groups in the risk of other adverse effects. No beneficial effects of Lactobacillus GG were observed for H. pylori eradication rates (four RCTs, n = 284, RR 0.99, 95% CI 0.88 - 1.13). Conclusion: Current evidence indicates that Lactobacillus GG administered along with standard triple therapy is a feasible way to reduce therapy-related side effects, particularly diarrhea, bloating, and taste disturbance. However, Lactobacillus GG shows no effects on eradication rates.

Standard triple, bismuth pectin quadruple and sequential therapies for Helicobacter pylori eradication

AIM: To compare the effectiveness of standard triple, bismuth pectin quadruple and sequential therapies for Helicobacter pylori (H. pylori ) eradication in a randomized, double-blinded, comparative clinical trial in China. METHODS: A total of 215 H. pylori -positive patients were enrolled in the study and randomly allocated into three groups: group A (n = 72) received a 10-d bismuth pectin quadruple therapy (20 mg rabeprazole bid , 1000 mg amoxicillin bid , 100 mg bismuth pectin qid , and 500 mg levofloxacin qd ); group B (n = 72) received the sequential therapy (20 mg omeprazole bid , 1000 mg amoxicillin bid , in 5 d, followed by 20 mg omeprazole bid , 500 mg tinidazole bid , 500 mg clarithromycin bid , for another 5 d); group C (n = 71) received a standard 1-wk triple therapy (20 mg omeprazole bid , 1000 mg amoxicillin bid , 500 mg clarithromycin bid ). After all these treatments, 20 mg omeprazole bid was administrated for 3 wk. H. pylori status was assessed by histology, 13C-urea breath test and rapid urease test at baseline and 4-6 wk after completion of treatment. Ulcer cicatrization was assessed by gastroscopy. χ 2 test (P < 0.05) was used to compare the eradication rates and ulcer cicatrisation rates among the three groups. RESULTS: The eradication rate was 83.33% (60/72) in group A, 88.89% (64/72) in group B, and 80.56% (58/71) in group C. The ulcer cicatrisation rate was 86.44% (51/59) in group A, 90.16% (55/61) in group B, and 84.91% (45/53) in group C. The sequential therapy yielded a higher eradication rate and ulcer cicatrisation rate than the standard triple and bismuth pectin quadruple therapies. Statistically, the eradication rate of group B was significantly different from groups A and C (P < 0.05), but the difference of ulcer cicatrisation rate and side effects was not statistically significant among the three groups (P > 0.05). The three protocols were generally well tolerated. CONCLUSION: The sequential therapy has achieved a significantly higher eradication rate, and is a more suitable first-line alternative protocol for anti-H. pylori infection compared with the standard triple and bismuth pectin quadruple therapies.

Fourteen- vs seven-day bismuth-based quadruple therapy for second-line Helicobacter pylori eradication

AIM: To compare the efficacy of 14- and 7-d bismuthbased quadruple therapies as second-line eradication treatment for Helicobacter pylori(H.pylori) infection.METHODS: Between 2004 and 2014,the medical records of 790 patients who had experienced failure of first-line proton pump inhibitor(PPI)-based eradication therapy and were then treated with bismuth-based quadruple therapy were retrospectively reviewed.Those who received bismuth-based quadruple therapy [PPI,bismuth,metronidazole,and tetracycline(PBMT)] for either 7 d or 14 d were assigned to a PBMT-7 group(n = 543) or a PBMT-14 group(n = 247),respectively.The eradication rates for both groups were determined by intention-to-treat(ITT) and per-protocol(PP) analyses.ITT analysis compared the treatment groups as originally allocated while the PP analysis including only those patients who had completed the treatment as originally allocated.Successful eradication therapy for H.pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of eradication treatment.RESULTS: The overall ITT eradication rate was 69.1%(546/790).Final ITT eradication rates were 67.4%(366/543; 95%CI: 63.1%-71.7%) in the PBMT-7 group and 72.8%(180/247; 95%CI: 67.4%-78.2%) in the PBMT-14 group(P = 0.028).The overall PP eradication rate was 80.0%(546/682),and the final PP eradication rates were 78.2%(366/468; 95%CI: 72.1%-84.0%) in the PBMT-7 group and 84.1%(180/214; 95%CI: 76.8%-90.8%) in the PBMT-14 group(P = 0.009).The H.pylori eradication rates in the PBMT-14 group weresignificantly higher than in the PBMT-7 group according to both ITT(P = 0.028) and PP analysis(P = 0.009).Compliance was similar in both groups(PBMT-7 group: 97.9%; PBMT-14 group: 96.4%).Adverse event rates were 10.7%(51/478) and 17.1%(38/222) in the PBMT-7 and PBMT-14 groups,respectively(P = 0.487).CONCLUSION: The 14-d bismuth-based quadruple therapy is a significantly more effective second-line eradication treatment for H.pylori infection than the 7-d alternative.

Efficacy of 14-d vs 7-d moxifloxacin-based triple regimens for second-line Helicobacter pylori eradication

AIM: To evaluate the efficacy of the 14-d moxifloxacinbased triple therapy for the second-line eradication of Helicobacter pylori(H. pylori) infection.METHODS: Between 2011 and 2013, we conducted a retrospective review of the medical records of 160 patients who had experienced failure of their first-line proton pump inhibitor-based eradication therapy and subsequently received the moxifloxacin-based triple therapy as a second-line eradication treatment regimen. The patients who were treated with the moxifloxacinbased triple therapy(oral 20 mg rabeprazole b.i.d., 1000 mg amoxicillin b.i.d., and 400 mg moxifloxacin q.d.) for 7 d were assigned to the RAM-7 group(n = 79) while those who took them for 14 days were assigned to RAM-14 group(n = 81). The eradication rates for both groups were determined by intentionto-treat(ITT) and per-protocol(PP) analyses. ITT analysis compared the treatment groups as originally allocated while the PP analysis including only those patients who had completed the treatment as originally allocated. Successful eradication therapy for H. pylori infection was defined as the documentation of a negative 13C-urea breath test 4 wk after the end of the eradication treatment.RESULTS: The overall ITT eradication rate was 76.2%(122/160). The final ITT eradication rates were 70.8%(56/79; 95%CI: 63.3%-77.1%) in the RAM-7 group and 81.4%(66/81; 95%CI: 74.6%-88.3%) in the RAM-14 group(P = 0.034). The overall PP eradication rate was 84.1%(122/145), and the final PP eradication rates were 77.7%(56/72; 95%CI: 70.2%-85.3%) in the RAM-7 group and 90.4%(66/73; 95%CI: 82.8%-98.1%) in the RAM-14 group(P = 0.017). The H. pylori-eradication rates in the RAM-14 group were significantly higher compared with that of the RAM-7 group according to both the ITT(P = 0.034) and the PP analyses(P = 0.017). Both groups exhibited good treatment compliance(RAM-7/RAM-14 group: 100%/100%). The adverse event rates were19.4%(14/72)and 20.5%(15/73)in the RAM-7 and RAM-14 groups,respectively(P=0.441).Adverse events occurred in 14 of the 72 patients(19.4)in the RAM-7 group and in 15 of the 73 patients(20.5)in the RAM-14 group.No statistically significant differences(P=0.441)were observed.CONCLUSION:The 14-d moxifloxacin-based triple therapy is a significantly more effective secondline eradication treatment as compared to the 7-d alternative for H.pylori infection in South Korea.

Efficacy of moxifloxacin-based sequential therapy for first-line eradication of Helicobacter pylori infection in gastrointestinal disease

AIM:To evaluate the efficacy of 14-d moxifloxacinbased sequential therapy as first-line eradication treatment of Helicobacter pylori(H.pylori) infection.METHODS:From December 2013 to August 2014, 161 patients with confirmed H.pylori infection randomly received 14 d of moxifloxacin-based sequential group(MOX-ST group, n = 80) or clarithromycin-based sequential group(CLA-ST group, n = 81) therapy.H.pylori infection was defined on the basis of at least one of the following three tests:a positive 13C-urea breath test; histologic evidence of H.pylori by modified Giemsa staining; or a positive rapid urease test(CLOtest; Delta West, Bentley, Australia) by gastric mucosal biopsy.Successful eradication therapy for H.pylori infection was defined as a negative 13C-urea breath test four weeks after the end of eradication treatment.Compliance was defined as good when drug intake was at least 85%.H.pylori eradication rates, patient compliance with drug treatment, adverse event rates, and factors influencing the efficacy of eradication therapy were evaluated.RESULTS:The eradication rates by intention-to-treat analysis were 91.3%(73/80;95%CI:86.2%-95.4%)in the MOX-ST group and 71.6%(58/81;95%CI:65.8%-77.4%)in the CLA-ST group(P=0.014).The eradication rates by per-protocol analysis were 93.6%(73/78;95%CI:89.1%-98.1%)in the MOX-ST group and 75.3%(58/77;95%CI:69.4%-81.8%)in the CLAST group(P=0.022).Compliance was 100%in both groups.The adverse event rates were 12.8%(10/78)and 24.6%(19/77)in the MOX-ST and CLA-ST group,respectively(P=0.038).Most of the adverse events were mild-to-moderate in intensity;there was none serious enough to cause discontinuation of treatmentin either group.In multivariate analysis,advanced age(≥60 years)was a significant independent factor related to the eradication failure in the CLA-ST group(adjusted OR=2.13,95%CI:1.97-2.29,P=0.004),whereas there was no significance in the MOX-ST group.CONCLUSION:The 14-d moxifloxacin-based sequential therapy is effective.Moreover,it shows excellent patient compliance and safety compared to the 14-d clarithromycin-based sequential therapy.

Statistical proof of Helicobacter pylori eradication in preventing metachronous gastric cancer after endoscopic resection in an East Asian population

We conducted a comprehensive literature review and meta-analysis study on the efficacy of Helicobacter pylori(H. pylori) eradication in preventing metachronous gastric cancer after endoscopic resection among an East Asian population. Our results showed that the eradication of this pathogen significantly reduced the risk of susceptibility to metachronous gastric cancer in these patients. However, based on the available evidence, several factors such as increasing age, severe atrophy in the corpus and antrum, and intestinal metaplasia all may increase the risk of metachronous gastric cancer in H. pylori eradicated patients.

Antimicrobial susceptibility testing before first-line treatment for Helicobacter pylori infection in patients with dual or triple antibiotic resistance

To evaluate the efficacy of antimicrobial susceptibility-guided therapy before first-line treatment for infection in patients with dual or triple antibiotic resistance.METHODSA total of 1034 patients infected by Helicobacter pylori (H. pylori) during 2013-2014 were tested for antimicrobial susceptibility. 157 of 1034 (15%) patients showed resistance to two (127/1034; 12%) and to three (30/1034; 3%) antibiotics. Sixty-eight patients with dual H. pylori-resistance (clarithromycin, metronidazole or levofloxacin) were treated for 10 d with triple therapies: OAL (omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and levofloxacin 500 mg b.i.d.) 43 cases, OAM (omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg b.i.d.) 12 cases and OAC (omeprazole 20 mg b.id., amoxicillin 1 g b.i.d., and clarithromycin 500 mg b.i.d.) 13 cases based on the antimicrobial susceptibility testing. Twelve patients showed triple H. pylori-resistance (clarithromycin, metronidazole and levofloxacin) and received for 10 d triple therapy with OAR (omeprazole 20 mg b.id., amoxicillin 1 g b.i.d., and rifabutin 150 mg b.i.d.). Eradication was confirmed by 13C-urea breath test. Adverse effects and compliance were assessed by a questionnaire.RESULTSIntention-to-treat eradication rates were: OAL (97.6%), OAM (91.6%), OAC (92.3%) and OAR (58.3%). Cure rate was significantly higher in naïve patients treated with OAR-10 compared to patients who had two or three previous treatment failures (83% vs 33%). Adverse events rates for OAL, OAM, OAC and OAR were 22%, 25%, 23% and 17%, respectively, all of them mild-moderate.CONCLUSIONAntimicrobial susceptibility-guided triple therapies during 10 d for first-line treatment leads to an eradication rate superior to 90% in patients with dual antibiotic H. pylori resistance.

Treatment of Helicobacter pylori in surgical practice:A randomised trial of triple versus quadruple therapy in a rural district general hospital

AIM: To compare a lansoprazole-based triple versus quadruple therapy for Helicobacter pylori (H pylori) eradication with emphasis on side effect prof ile,patient compliance and eradication rate at a rural district general hospital in Wales,United Kingdom. METHODS: One hundred one patients with H pylori infection were included in the study. Patients were randomised to receive triple therapy comprising of lansoprazole 30 mg,amoxycillin 1 g,clarithromycin 500 mg,all b.d. (LAC),or quadruple therapy comprising of lansoprazole 30 mg b.d.,metronidazole 500 mg t.d.s.,bismuth subcitrate 240 mg b.d.,and tetracycline chloride 500 mg q.d.s. (LMBT). Cure was defi ned as a negative 13C urea breath test 2 mo after treatment. RESULTS: Seven patients were withdrawn after randomisation. Fifty patients were assigned to LAC group and 44 to LMBT group. The intention-to-treat cure rates were 92% and 91%,whereas the per-protocol cure rates were 92% and 97%,respectively. Side effects were common,with 56% experiencingmoderate to severe symptoms in the LAC group and 59% in the LMBT group. Symptoms of vomiting,diarrhoea and black stools were significantly more common in the LMBT group. Patient compliance was 100% for triple therapy and 86% for quadruple therapy (P < 0.01). One-third of patients in both groups were still taking acid-reducing medications at six-month follow-up. CONCLUSION: One-week triple and quadruple therapies have similar intention-to-treat eradication rates. Certain side effects are more common with quadruple therapy,which can compromise patient compliance. Patient education or modifi cations to the regimen are alternative options to improve compliance of the quadruple regimen.
